This paper analyses best practices of sediment management for ports and shipyards, including relevant legal issues and applicable training requirements for personnel. The disposal options by using innovative technologies are analysed and presented considering their technical aspects, application requirements, safety aspects, training needs and the need to keep operational costs within acceptable ranges.

Ship ballast water is a recognized medium for transfer and introductions of nonindigenous species. There is a need for new ballast water treatment methods that effectively and safely eliminate or greatly minimize movements of these species. The present study employed laboratory methods to evaluate the bactericidal efficacy of increased pH (pH 10.0–12.0) for exposure durations of up to 72 h to kill a variety of Gram-negative and Gram-positive bacteria including fish pathogens (Aeromonasspp., Yersinia ruckeri, Edwardsiella ictaluri, Serratia liquefaciens, Carnobacterium sp.

Treatment of ship ballast water with sodium hydroxide (NaOH) is one method currently being developed to minimize the risk to introduce aquatic invasive species. The bactericidal capability of sodium hydroxide was determined for 148 bacterial strains from ballast water collected in 2009 and 2010 from the M/V Indiana Harbor, a bulk-freight carrier plying the Laurentian Great Lakes, USA. Primary culture of bacteria was done using brain heart infusion agar and a developmental medium. Strains were characterized based on PCR amplification and sequencing of a portion of the 16S rRNA gene.

In the past, ships used solids as ballast; this included metals, sand and rocks. Today, ships use sea water as ballast and it is referred to as ballast water. It is therefore very normal for ships to pump in ballast water at one port and discharge at the loading port before taking cargo. In this chapter you will be able to understand ballast water.
